X-Grip SIG SAUER P320/250SC Mag Adapter

This X-Grip mag adapter lets SIG Sauer P320/250SC pistols accept the larger P320/250 full-size magazines by integrating the full-size magazine footprint into the subcompact grip for increased capacity. It installs without tools and is designed to seat over the magazine floorplate for a secure fit. For mounting a red-dot on a P320/250SC setup, a compact pistol optic such as the Holosun 407K pairs well and stays well under $1,000.

Common uses include range training to maintain longer sessions between reloads and competition/practical shooting applications where higher magazine capacity in a subcompact grip is desired.
